That was the way the city’s Central Service grew. As more computers were assigned to various tasks, engineers were hired to coordinate them, to link them with special circuits and to set up central “data tanks,” so that a traffic regulator in the north end would be aware of traffic conditions in the main thoroughfares to the south. Then, when the micro-learner relay was invented, the engineers built a central unit to be used in conjunction with the central data tanks. With the learning units in operation, Central was able to perform most of the city’s routine tasks without attention from human supervisors.
The system had worked well. Apparently it was still working well three years after the inhabitants had fled before the chatter of the Geiger counters. In one sense Ferris had been right: A city whose machines carried on as if nothing had happened—that city might be a dangerous place for a lone wanderer.
But dynamite certainly wasn’t the answer, Mitch thought. Most of man’s machinery was already wrecked or lying idle. Humanity had waited a hundred thousand years before deciding to build a technological civilization. If it wrecked this one completely, it might never build another.
Some men thought that a return to the soil was desirable. Some men tried to pin their guilt on the machines, to lay their own stupidity on the head of a mechanical scapegoat and absolve themselves with dynamite. But Mitch Laskell was a man who liked the feel of a wrench and a soldering iron—liked it better than the feel of even the most well-balanced stone ax or wooden plow. And he liked the purr of a pint-sized nuclear engine much better than the braying of a harnessed jackass.
He was willing to kill Frank Ferris or any other man who sought to wreck what little remained. But gloom settled over him as he thought, “If everybody decides to tear it down, what can I do to stop it?” For that matter, would he then be right in trying to stop it?
At sundown he came to the limits of the city, and he stopped just short of the outskirts. Three blocks away a robot cop rolled about in the center of the intersection, rolled on tricycle wheels while he directed the thin trickle of traffic with candy-striped arms and with “eyes” that changed color like a stoplight. His body was like an oil drum, painted fire-engine red. The head, however, had been cast in a human mold, with a remarkably Irish face and a perpetual predatory smile. A short radar antenna grew from the center of his head, and the radar was his link with Central.
Mitch sat watching him with a nostalgic smile, even though he knew such cops might give him considerable trouble once he entered the city. The “skaters” were incapable of winking at petty violations of ordinance.
As the daylight faded, photronic cells notified Central, and the streetlights winked on promptly. A moment later, a car without a taillight whisked by the policeman’s corner. A siren wailed in the policeman’s belly. He skated away in hot pursuit, charging like a mechanical bull. The car screeched to a stop. “O’Reilly” wrote out a ticket and offered it to any empty back seat. When no one took it, the cop fed it into a slot in his belly, memorized the car’s license number, and came clattering back to his intersection, where the traffic had automatically begun obeying the ordinances governing nonpoliced intersections.
The cars were empty, computer-piloted. Their destinations were the same as when they had driven regular daily routes for human passengers: salesmen calling on regular customers, inspectors making their rounds, taxis prowling their assigned service areas.
Mitch Laskell stood shivering. The city sounded sleepy but alive. The city moved and grumbled. But as far as he could see down the wide boulevard, no human figure was visible. The city was depopulated: There was a Geiger on a nearby lamppost. It clucked idly through a loudspeaker. But it indicated no danger. The city should be radiologically safe.
But after staring for a long time at the weirdly active streets, Mitch muttered, “It’ll wait for tomorrow.”
He turned onto a side road that led through a residential district just outside the city limits. Central’s jurisdiction did not extend here, except for providing water and lights. He meant to spend the night in a deserted house, then enter the city at dawn.
Here and there a light burned in one of the houses, indicating that he was not alone in his desire to return. But the pavement was scattered with rusty shrapnel, with fragments fallen from the sky battles that still continued. Even by streetlight he could see that some of the roofs were damaged. Even though the bombers came without bombs, there was still danger from falling debris and from fire. Most former city dwellers who were still alive preferred to remain in the country.
